Propagation of THz waves from 0.1THz to 0.8THz in sand-dust are studied using Mie theory and Monte Carlo(MC) simulation. Scattering characteristics of a spherical sand-dust particle illuminated by THz waves are analyzed by Mie theory. The extinction efficiency factor, the asymmetry parameter and scattering intensity versus frequency of incident waves are computed. With MC algorithm, the reflectivity,...
Dust aggregates in plasma charge, which makes it difficult to study the propagation of electromagnetic wave in it. While in order to study the influence of charged dust to the space detection, some work must be done for the electromagnetic characteristic of it. Based on discrete dipole approximation (DDA), electromagnetic scattering characteristic of charged dust aggregates is studied. At the beginning,...
Based on Debye series of an infinite homogeneous cylinder and a multi-layered sphere, and incorporating with the Gaussian beam shape coefficient in the circular cylindrical coordinates, Debye series of electromagnetic scattering by an infinite multi-layered cylinder in a Gaussian beam is discussed, and the formula is obtained. Some numerical calculations are also given. Comparing with generalized...
